TLS version others.
Just for anyone with this problem here was the response from my web host. It may be applicable to.
"Thank you for providing the code details. Looking at the PHP version which CURL is tied to. PHP was set to 5.4.32. The CURL version was 7.36. According to CURL documentation on their website, TLS 1.2 was introduced in Curl version 7.38.
The best solution to this was to set the site to run PHP version 7.1.1 which is installed on the server. The Curl version is 7.51 using PHP 7.1.1 which supports TLS 1.2. I have made this adjustment. PHP pages are loading, but changing version of PHP can break website functionality. In such instances where website functionality breaks, you would need to have your website upgraded with your application vendor to support PHP 7.1.1, Curl 7.51, and TLS 1.2. If you find this change has broken functionality, we can revert the site back to using PHP 5.4.32 and Curl 7.36 until your application provider or your developer can assist you in upgrading your application code. Please keep us posted."
